I dislike the ballcap style, every balding redneck here feels it's a necessary accessory. I'd rather see no hat than that type. I do like the formal "smokey bear" style though, serious intimidation factor, especially when paired with a nice, dark pair of sunglasses.
When wearing my Smokey hat I have noticed much less attitude from problem people. For large scale traffic direction details specifically wrecks they are a big help.
Motorway, does the "special" hat come with a siren as well? :P
(What would Raylan Givens do?)
